I am currently running simulation of rotating airfoils using the cyclicAMI Mesh. For previous runs (different mesh) I had no problem restarting the run if it blew or ran out of time from the latestTime. I then changed the number of airfoils from 3 to 2 in my mesh while keeping every other parameter the same. Now when I try to restart the run I get this error:

I have faced similar problem couple of times.
I guess it is the problem with your memory where openFoam is installed. I guess there is no sufficient space to write the files further. I usually delete my previous cases and then make some free space and I run the case again the case works fine. I am not sure if it works, but give it a try |

One can use the purgeWrite keyword in controlDict to get rid of some of the time steps. For example, if you want only the last three time steps of your simulations at any given time, set purgeWrite= 3.
